NetLogo: How to make turtles (1) move to a patch with patch variable matching condition based on turtle variable and (2) take patch id as variable

Question

I'm trying to do the following:

1. Ask turtles (households here) to check whether there are any patches that have (1) is-home = true and (2) cost less than the household's money;
2. Take as my-home the patch id of the first patch that meets these qualifications;
3. Pass the household id to the patch's patch-owner variable; and
4. Move to that patch.
5. If they don't find a patch that meets the criteria, the household dies and the displaced counter increments by 1.

UPDATE: Thanks for the assists so far. Now after adding the condition and not any? households-here to prevent households from occupying the same patches, pressing Go triggers the error MOVE-TO expected input to be an agent but got NOBODY instead. Sorry to reopen this question, but can anyone provide further guidance?

I see a few problems with your code.

setup-households: You never actually create any turtles. You only ask the (nonexistent) turtles to change their money.

setup-patches: I'm not sure what you are doing here. You ask 100 patches to maybe become a home and maybe not become a home. Why not just ask 50 patches to become a home? Or ask all patches to become a home but adjust your world size to the number of homes you want? I would also suggest to use scale-color, in order to visualise the cost of all patches.

choose-house: You are trying to check the money of myself, without actually having a myself available (currently it is called by the observer). Moving ask households to the start of the procedure fixes this. I should note that currently multiple households can move into the same house. Finally, you misspelled turtles-here

to choose-house
  ask households [ 
    ifelse any? patches with [ is-home? = true and cost <= [money] of myself ] [ 
      
      move-to one-of patches with [ is-home? = true and cost <= [money] of myself ]
      set owner? true
      set my-home patch-here
      set my-owner turtles-here
    ] [
      set number-displaced number-displaced + 1
      die 
    ]
  ]
end
